Description

Technical Field

[0001] The utility model relates to the technical field of capacitor detection, in particular to a voltage detection device for processing solid-state capacitors. Background Art

[0002] Capacitors are electrical components that stabilize the current in the circuit, so that the voltage in the circuit will not change suddenly. After the production and processing of capacitors, they need to be tested for voltage to detect whether the quality specifications of the produced capacitors meet the production requirements and improve the factory quality of the capacitors. However, the existing capacitor voltage detection device cannot perform continuous detection, which leads to low detection efficiency.

[0003] To solve the above problem, there is a solution of a voltage detection device for fixed capacitor processing (Announcement No. CN213986612U). The tester can add capacitors to other placement slots during the test; after the test is completed, the lifting rod rises and the mounting plate rotates, so that the capacitors after the test are transferred out, and the untested ones are transferred to the bottom of the test set, and then the next test is carried out, thereby realizing continuous testing.

[0004] However, when the above scheme is used, the staff needs to check the voltmeter and alarm to confirm whether the capacitor is qualified after placing the capacitor, and manually distinguish qualified capacitors from unqualified capacitors. There are problems of operating errors in the manual area, and the detection efficiency will also be affected by manually placing and distinguishing capacitors. The above scheme needs to be improved in the degree of automation of capacitor-assisted detection. Utility Model Content

[0005] The purpose of the utility model is to provide a voltage detection device for solid capacitor processing to solve the problems raised in the above background technology.

[0007] The two belts are used to position the solid-state capacitor through the limit seat. When the servo motor drives the belt to move through the roller, the solid-state capacitor moves to the bottom of the measuring head, realizing the automatic transportation of the solid-state capacitor.

[0008] A support plate, the support plate is connected to the surface of the detection table, a lower pressure electric cylinder is installed on the surface of the support plate, an assembly seat is installed at the lower end of the lower pressure electric cylinder, two sliding columns are plugged on the assembly seat, a limit wire is installed on the upper end of the sliding column, and the limit wire is located above the assembly seat, a spring is sleeved on the sliding column, and a measuring head is installed at the lower end of the sliding column;

[0009] The measuring head is controlled to move downward by pressing the electric cylinder, and the measuring head can be buffered by the spring to prevent the measuring head from excessively squeezing the solid-state capacitor, thereby providing good protection.

[0010] Furthermore, two material discharge holes are provided on the surface of the testing platform, two material guide tubes are provided on the lower surface of the testing platform, two material barrels are placed inside the testing platform, and the two material barrels are located below the two material guide tubes. The two material discharge holes can send qualified and unqualified solid-state capacitors to the two material barrels, thereby realizing the distinction between solid-state capacitors.

[0011] Furthermore, two pushing electric cylinders are installed on the surface of the testing table, and the two pushing electric cylinders are located on the sides of the two feeding holes. Pushing plates are installed on the pushing electric cylinders. The solid-state capacitors are pushed into the feeding holes by the two pushing electric cylinders, and there is no need to manually distinguish between qualified and unqualified solid-state capacitors.

[0012] Furthermore, two power connection posts are provided on the surface of the assembly seat, and electric wires are connected between the power connection posts and the corresponding measuring heads. An instrument for measuring solid-state capacitors is connected to the two power connection posts, which facilitates detection.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The solid-state capacitors are placed on the limit seat on the belt. When the belt is running, the sorted solid-state capacitors are driven to move toward the bottom of the measuring head. The downward pressure electric cylinder controls the measuring head to move down and contact the electrodes of the solid-state capacitors for measurement. The push cylinder distinguishes the solid-state capacitors according to the measurement results, and stores qualified and unqualified solid-state capacitors in two buckets. The detection efficiency is higher and there will be no problem of misidentifying solid-state capacitors.

[0015] (2) The spring keeps the measuring head housing in stable contact with the solid-state capacitor to avoid poor contact. At the same time, the spring acts as a buffer for the measuring head. When the measuring head moves down, the solid-state capacitor will not be crushed, which provides good protection for the solid-state capacitor during detection. BRIEF DESCRIPTION OF THE DRAWINGS
